One time I had a very interesting experience happen too me.I attended a UPC church for 2 years and God directed me to start attending a Word Church. About a year later I grew my beard back, and one day I just had a desire in my heart to go to worship at my old UPC church. I really felt the hand of God in this but before I went in, I asked God to not let me Prophesy in tongues, because I knew that these people would not recieve it because they thought that I had back slidden because I left their church. Plus I had a beard and that's pretty unexceptable there.Things went really great until the worship got real quiet. I tried really hard with every thing in me not to prophecy in tongues but I just felt it so strongly that I couldn't hold it back! Sure enough no one interpretted it, not even the pastor.When I left I was so frustrated. I told God I asked you not to let me do that?There was no explaination from Him.2weeks later, I was visiting with a friend. A young pentecostal girl stopped by to visit and as my friend introduced me to her, the young girl said," I know you, you where that guy that prophecied in our church a while back". I said ,"yes" She said," That day my father was visiting our church, he had been backslidden and had not been to church for years. He travels over seas alot with his job. When you prophecied in tongues that morning He asked if you spoke malaysian? we said probably not!He said, " that man is speaking directly to me in the most perfect malaysian language I've ever heard.He gave his life back to the Lord that day!God is so awesome!
